Theinvention, as shown'by lsaid oval lor head portion oa' racket, `comprises in its main parts or elements, the frame 10, `the intermediate throat member 1 1, tl'1ethroat piecel2, the strengthening and protecting "bushings 13,v and the net 14.

In common practice a tube of metal, preferably. of Vlight metalsuch as magnesiumVis furnished in desirable racket frame length, and substantially lof rectangular cross sectional area. The tube length is then bent to racketforin of conventionalor. desired pattern.

When. the frame has reached .this form the metal is not stift' enough to make a rigid frame, and in the case of magnesium, which may .not be temperedflike forms of other metalsby heat treatment,.it becomes necesy sary to work the metal in order to give it v the necessary's't-il'ness.. f f This is accomplished bytaking the conventionalframe of rectangular formtubing shownl byFig. 4, and indenting it as .indicated in Fig( 5 on opposite sides, .as at 15 and 16, the squeezing actiony incident to :this indenting. causing the other. two sides. of the rectangle to bulgeas at l''and 18, 5. "Thus,.byrhe-atoiinde .ingt'he meta 011 two sides, all four sidesg fthe rectangular tube are. manipulated. A

Thel bulged Side, of f he `tubing is then rolled between rolls 'and attened bac'zk again as indicated at. 19 and 20, Fig. 6, and this 'tionand in. which .Figure lisa yface yor plan action further reworks the two bulged sides,

so that vthe ymanipulation of :the magnesium metal vsets up crystallizing strains which tend to reset the molecules of the metal within the frame; or tube and causethe tube t0 become: laterallyifnruch stifer than whenV the metal is in its natural or normal condition.

It Will, therefore, be noted that r.a Afr ame such as 10 is providedWhichfismadestrongand rigid in a transverseplane, first, bythe inden't'fing of the sides as a 4mechanical rneans and secondly, :by causing the metal Within the frame tobe Worked thereby settingup hardening strains so that the final article is` very much stiffer thanv it would be if the dition, vthe "framey 10 thus vhaving concave outer andinner sides and' straight or flat upper-and under sides.

Y The intermediate throat or bridge member 11 is of the same tubing as the frame 10 having concave outer and inner sides and `straight lorglat upper and under sides andv is curved or tbowed towards the handle' portion, not shown, to conform to the bend yotl the :frame 1() and complete the oval shape of t'he head of theraclret.A The throat melnber -11is Secured to the frame 10, as by the pins 212 and 21, passing through thethroa-t mem-v ber rand :through'the frame 10, and is aryrangedadj acent to the throat piece or Wedge 12, the upper 'edge of the throat piece 12 be "ingreceived in the outer concave or indented "'side of the throat member y11 for securing these members together. v

F or further strengthening the `frame 10 and forvthe further purpose of preventing abrasion or' strings of the net 14, the frame and Z-cl With aA series vof openings 22 and23 through the outer and inner concave sides of they tubing of the frame, the' openings v23 inthe inner side of the tubing substantially registering with the openings`22 inthe outer side of the. tubing, the openings 23 each havon its inner, edge an annular rabbet 24, `ig. 2. t

.The bushings 13 `preferably are of the same material as the tubing 10. Each of these bushings or eyelets comprises the body portion '25, the outer head 26, the innerv head 27 and thecap 28 on the inner `hea;d,.i3he cap 28 forming an annular' flange. Each bu shing has a. bore :2.9 therethrough, the bore 29'flaring outwardly at both endsor mouths ofthe bushings, Figs.' 2 and.3. l Y c The'bushings 13 are Y"forced into the openings fofthetubing 10,' Vfrom the Vinner side'of 'the'f-.tuhinggthe outer heads 26 ojthe'ibu'shextent kblntliigl1orf molding therewith at the' points of engagement. It isthusseen that j these bushings provide a transverse strengthening means for the trame 10 at the beforelmentioned sections of the frame.

VoLt the racket, and ythat-in use of the rachet and impact of the ball upon the net there is a tendency of th-e edge ,of the frame at such angles to Wear or abrade the strings. In the present instance by means of the Haring ends or-mouths of the bores of the bushings 13 the acuteness of the angle is obviated and all possibility .of abrasion of the strings by the edges of the tubing is removed, While the looped ends, not seen, of `the strings lie in the concave outer side of thetubingiand are protected thereby. 'The bushings 13a onk op- ,posite sides of the frame 10 passing'through the tubi-ng landthe throat member '11, are in all respects the same as the E'bushings 13 except that they 'are of greater length, the

lopenings for receiving these bushings however extending throughl 'the throat `member and rhav-ing'ra`bbets,' seen inV `1, ,on the inner sides of fthe throatmember corresponding to the rabbets 24.on'gthe innerside ofthe tubing forming the frameV 10.: Y

"For .strings of the netl .14 which pass through the frame either in straight 'lines' or at'obtuse angles and are not so liablel to abrasion, registering lacingfholes such asf33 are provided Wherefrequired through the tubing of the frame 10; v
